It wears Red Quartz Tintcoat — a deep, metallic red — with a Jet Black interior finished in Forge Perforated Leather-Appointed seat trim, and it arrives ready to work: gooseneck/5th-wheel prep, an integrated trailer brake controller, and the ProGrade Trailering System are already on board.

The hauling credentials here go beyond the basics. The Gooseneck/5th Wheel Package adds a hitch platform to accept a gooseneck or 5th-wheel hitch, giving this truck flexibility most pre-owned heavy-duties don't have configured from the factory.
The integrated trailer brake controller, ProGrade Trailering System, and HD Surround Vision with two trailer view camera provisions mean you can hook up and monitor a large trailer with confidence. A 120-volt bed-mounted power outlet and LED cargo area lighting round out the working end of the truck.
The Technology Package and Preferred Equipment Group 5SA bring the Denali's comfort and driver-assistance story together. Up front, heated and ventilated front bucket seats and heated second-row outboard seats keep every occupant comfortable year-round.
The multicolor 15-inch diagonal head-up display, rear camera mirror with full camera display, and bed view camera keep the driver oriented. On the road, the X31 Off-Road Package , Driver Alert Package I and II (which includes forward collision mitigation), and a remote vehicle starter system add all-season confidence.
Wireless charging, a premium GMC infotainment system with navigation and an 8-inch color touch screen, a universal home remote, and a 220-amp alternator round out the feature set. The all-weather floor liners (1st and 2nd rows) and spray-on pickup box bed liner with Denali logo were also fitted from the factory.
One owner reported, no accidents reported to Carfax — this Denali has a straightforward history for a truck with serious equipment. At 97,200 miles on a diesel powertrain known for longevity, and a factory-prepped gooseneck/5th-wheel platform, it's a ready-to-work truck for the buyer who doesn't want to spend time sourcing a hitch prep after the fact.
Napleton Buick GMC is at 6305 Northwest Hwy, Crystal Lake, IL — on US-14 along the Metra UP-NW line, a short drive for shoppers coming from Cary, Algonquin, and Lake in the Hills. We're a family-owned group with more than 80 years in the area, and we'd rather show you the truck than sell you on it.
